Abstract

Objectives: Temporal bone fracture can cause posttraumatic deafness. Sequelae like ossification or obliteration of the cochlea can impact the outcome of cochlear implantation. This study highlights the effect of localisation of the fracture to morphologic, electric and functional criteria.

Methods: The study group consists of patients suffering from hearing loss caused by temporal bone fracture (n = 61 ears). Patients were divided into otic capsule sparing (OCS) and otic capsule involving (OCI) fractures. The OCI group was additionally divided into subgroups with or without signs of ossification inside the cochlea. Postoperative imaging, hearing tests and electrode impedances were analysed.

Results: The results of postoperative hearing rehabilitation showed lower speech understanding scores for the OCI group, especially for the ossification group. OCI fractures with signs of ossification showed increased impedances. Patients in the OCI group suffered more frequently from facial nerve stimulation (FNS). FNS was most frequently observed within the ossification group.

Conclusion: Cochlear implantation in patients with temporal bone fracture is adequate therapy for the treatment of fracture-induced deafness. In long-term observation, these patients show comparable results with regular cochlear implant (CI) patients. Implantation should be performed as soon as possible after hearing loss, before obstructing obliteration or ossification of the cochlea start.

颞骨骨折后植入人工耳蜗的听觉康复-一项病例对照研究。

目的:颞骨骨折可引起创伤后耳聋。耳蜗骨化或闭塞等后遗症会影响人工耳蜗植入术的效果。这项研究强调了骨折的定位对形态学、电学和功能标准的影响。方法:以颞骨骨折致听力损失患者为研究对象(61耳)。将患者分为保留耳囊骨折(OCS)和伴有耳囊骨折(OCI)两组。OCI组又分为有或无耳蜗内骨化征象的亚组。术后影像学、听力检查及电极阻抗分析。结果:术后听力康复结果显示，OCI组言语理解评分较低，骨化组尤为明显。有骨化迹象的OCI骨折显示阻抗增高。OCI组患者更频繁地遭受面神经刺激(FNS)。FNS在骨化组中最为常见。结论:颞骨骨折患者人工耳蜗植入术是治疗骨折性耳聋的有效方法。在长期观察中，这些患者的结果与常规人工耳蜗(CI)患者相当。植入术应在听力丧失后，在耳蜗阻塞闭塞或骨化开始之前尽快进行。

期刊介绍： Cochlear Implants International was founded as an interdisciplinary, peer-reviewed journal in response to the growing number of publications in the field of cochlear implants. It was designed to meet a need to include scientific contributions from all the disciplines that are represented in cochlear implant teams: audiology, medicine and surgery, speech therapy and speech pathology, psychology, hearing therapy, radiology, pathology, engineering and acoustics, teaching, and communication. The aim was to found a truly interdisciplinary journal, representing the full breadth of the field of cochlear implantation.
